Answer: c) 1.31 × 10⁴N
Explanation:
Centripetal force is a force that causes a body to move in a circular path. The body possesses a centripetal acceleration.
According to newtons first law
Force = mass (m) ×acceleration (a)
Acceleration of a body moving in a circular path = v²/r where;
v is the velocity and r is the radius
Force = MV²/r
Given m = 250kg v = 96.5km/hr r = 13.7m
We need to convert 96.5km/hr to m/s
= 96.5km ×1000/1hr × 3600
= 96,500/3,600
v = 26.8m/s
Force = 250 × 26.8²/13.7
Force = 13,106.5N
The centripetal force = 13,106.5N
= 1.31 × 10⁴N
Answer:
The answer to your question is: vo = 25 m/s
Explanation:
data
a = -7.5 m/s²
d = 42 m
vf = 0 m/s
vo = ?
Formula
vf² = vo² - 2ad
Substitution
0² = vo² - 2(7.5)(42)
We clear vo from the equation
vo² = 2(7.5)(42)
vo² = 630 simplifying
vo = 25 m/s result
If you want to tell a friend about a fish you caught or a tree you cut down,
you're going to tell him WHERE you were ... its position in space, 3 numbers,
'x', 'y', and 'z' ... and also WHEN you were ... its position in time, one more
number.
Dimensions are numbers used to describe the location of a point, and the
difference in location between two points. With four numbers, you can exactly
describe the location of anything, and its distance from any other thing, in
space and time.
Answer:
c. 70 Ω
Explanation:
The R and R resistors are in parallel. The 2R and 2R resistors are in parallel. The 4R and 4R resistors are in parallel. Each parallel combination is in series with each other. Therefore, the equivalent resistance is:
Req = 1/(1/R + 1/R) + 1/(1/2R + 1/2R) + 1/(1/4R + 1/4R)
Req = R/2 + 2R/2 + 4R/2
Req = 3.5R
Req = 70Ω
